Hotforming of gobs: The precision glass moulding process yields the best results in both quality and cost if it works with precise preforms. These are usually acquired by pressing or hotforming of "gobs" of molten glass. This step is done by continuous glass melting and moulding in single-sided metal moulds.
Optical glass refers to a quality of glass suitable for the manufacture of optical systems such as optical lenses, prisms or mirrors.Unlike window glass or crystal, whose formula is adapted to the desired aesthetic effect, optical glass contains additives designed to modify certain optical or mechanical properties of the glass: refractive index, dispersion, transmittance, thermal expansion and ...
Gorilla Glass, the glass still used on the screen of the iPhone and almost every smartphone in the world, was one of the most consequential inventions in modern history. Without it, the smartphone ...
This formed the subsequent basis for producing the first soft glass and polymer structured fibers. Most photonic crystal fibers have been fabricated in silica glass, but other glasses have also been used to obtain particular optical properties (such as high optical non-linearity). There is also a growing interest in making them from polymer ...
Let The Light In. Sometimes, you really don't need a window treatment! We promise this isn't an easy out but practical decorating advice that most design-minded homeowners could easily overlook.
The optical square uses a pentaprism to reflect and refract a beam or sighting 90 degrees, it is used in pairs in surveying and in a singular block in metrology. In optical square A Horizon glass is placed at an angle of 120° with the horizon sight. The Index glass is placed at an angle of 105° with the Index sight.
Depression glass, with its rich history and intricate craftsmanship, is a staple at any and every antique store, but that doesn’t make these pieces a dime a dozen. During the Great Depression ...
Lampworking can be done with many types of glass, but the most common are soda-lime glass and lead glass, both called "soft glass", and borosilicate glass, often called "hard glass". Leaded glass tubing was commonly used in the manufacture of neon signs , and many US lampworkers used it in making blown work.
